Catechesis: The First Commandment

The purpose of this commandment is to require true faith and trust of the heart, which settles upon the only true God and clings to Him along. It is like saying, “See to it that you let Me alone be your God, and never seek another.” In other words, “Whatever you lack of good things, expect it from Me. Look to Me for it. And whenever you suffer misfortune and distress, crawl and cling to Me. I, yes, I will give you enough and help you out of every need. Only do not let your heart cleave to or rest on any other.”—LC I:4
